Editing Gram

'''Gram''' is a unit of mass in the metric system that is equivalent to one thousandth of a kilogram. The term "gram" is derived from the Greek word "gramma," which means "small weight."

== History ==

The gram was originally defined in 1795 as the absolute weight of a volume of pure water equal to a cube of one hundredth of a meter, and at the temperature of melting ice. This definition was slightly modified in 1799 to specify that the gram was the absolute weight of a volume of pure water equal to a cube of one hundredth of a meter, and at the temperature of melting ice, but later changed to the current definition in 1889.

== Usage ==

In everyday life, the gram is most commonly used to measure the mass of small objects, such as groceries and ingredients for cooking. In scientific contexts, the gram is used to measure the mass of chemicals and other substances.

== Conversion ==

The gram is part of the [[International System of Units]] (SI), which is based on the meter, kilogram, second, ampere, kelvin, mole, and candela. One gram is equal to 0.001 kilograms, 1,000 milligrams, or 1,000,000 micrograms.
